Record efficiency for perovskite-silicon triple-junction solar cells

Published:18.03.26 — EPFL and CSEM researchers have achieved a record 30% efficiency for triple-junction solar cells, which combine two thin-film perovskite cells and one silicon cell on a single device. The milestone could advance affordable next-generation solar technologies for space and terrestrial applications.

Nanodevice produces continuous electricity from evaporation

Published:19.02.26 — A nanodevice developed at EPFL produces an autonomous, stable current from evaporating saltwater by using heat and light to control the movement of ions and electrons.

Slippery ions create a smoother path to blue energy

Published:16.02.26 — By engineering lubricated interfaces inside nanopores, EPFL researchers have enabled ions to flow through a nanofluidic membrane with unprecedented speed and control. In addition to enhancing nanofluidic technologies, the innovation could help accelerate the development of next-generation osmotic energy harvesting.

When heat flows like water

Published:13.02.26 — EPFL researchers have shown theoretically that, in highly ordered materials, heat can flow toward warmer regions without violating the laws of thermodynamics. Their work could help design electronics that minimize heat loss.
